1. Name of the element and how it got its name
Re: The element is Zn and the real name is Zinc.
a. Who discovered it: zinc was discovered by Andreas Marggraf in (about) the year
400 B.C.
b. What was it discovered: Zinc was found by mistake. It's the German word for zink. And it was found in Greece.
2. Symbol Atomic Number, and Atomic Mass: 30, Zn, 65.38(2) 65.38(2)g·mol-1
a. Source of the Symbol: Solid
3. Number of protons, neutrons, and elements
a. Protons: 30
b. Neutrons: 35
c. Electrons: 30
4. Where it is found (air, water, land)and is what form (state of matter-solid, liquid, gas)
5. Physical facts:
a. Melting point: 787.15 °F
b. Boiling point: 1665 °F
c. Density: 7.14 g·cm−3
d. Abundance the Earth’s crust(crust include air, water, and land): 0.0078%
6. Uses A (how is the element used): It is needed by our body but only in minute amounts. Too much Zinc becomes a poison to us. One of the uses is in the Ship/Boat Industry. They put blocks of Zinc on metal parts/engines/hull etc.. This ensures that electric/ionic activity does not corrode the boat or engine or hull. The Zinc will sacrifice itself for the better of the rest.
7. Interesting facts: Are organism need to zinc.zinc's important in the diet focused on the issue of growth. When foods did not supply sufficient amounts of zinc, young men in Iran and Egypt were found to have impaired overall growth as well as impaired sexual maturation. These initial studies on zinc reflected some of the key functions served by this mineral, including regulation of genetic activity and balance of carbohydrate metabolism and blood sugar.
8. Source (I would expect 3 to be a minimal number):
a. Atomic number: 65.39 grams per mole
b. Atomic mass: 65.39 amu
c. symbol: zn
